The IP restrictions aren't necessary because the spammer is submitting the solution to the captcha, not the data-entry slave. This is how it works: * Spam software sees a captcha image * Spam software saves the image and submits it to a "captcha" queue (maybe with a web service or something). It then waits for a solution on a "solution" queue * Off in the third world, the data-entry guy sees the image on the "captcha" queue and solves it. He submits the solution to the "solution" queue. * Spam software submits the signup form with the newly acquired solution.
Both the 8086 and 8088 are "16-bit" processors (with 20-bit memory addressing, if you remember your segment+offset math). The 8088 just had a slow bus that moved 8 bits at a time.
Another form factor the XT brought us was the drive bay. "Half-height" drives were the same physical dimensions as CD-ROM drives today.
Think about what uses the most power in your home - lighting (usually standard light bulbs), appliances that generate heat or cooling, and appliances that have motors. None of these would benefit from low-voltage DC. Your electronic devices, especially the ones with wall warts, do not use much power. AC has advantages for some electronic devices as well, such as clock radios and amplifiers.
The submitter is confused. She showed two separate hacks in her presentation. One was getting around binary signing (pagefile trick), and the other was the undetectable rootkit called "Bluepill" (start a hypervisor and run Vista as a guest OS).
Keep in mind that your 32-bit game can only use 2GB because that's the memory limit per process. So maybe 2.5 or 3GB of RAM would help, but not 4. And you can use 3GB of RAM with any current 32-bit processor.
Why not rate-limit outgoing TCP port 443? If Skype needs 100 kbps over a connection to maintain unbroken voice output, limit each connection to 50 kbps. You could also limit it to bursts of traffic - full speed for 0.5 second at a time, then 4.5 seconds at 50 kbps. Real HTTPS (small outgoing requests and large incoming responses) would still be responsive under these conditions.
Now that we have things like Windows, MacOS X, KDE and Gnome, any of the older apps built on Motif, tk or Xaw looks like shit to me and don't work like I think they should. It's like using some purpose-built gui in DOS:
make xconfig
xpdf
gv
xterm
X-Chat
linuxconf
gvim
Xemacs
XCDRoast
Mplayer
However, I do still use and appreciate some of these apps. xterm is still the best terminal emulator, and xpdf is still the best PDF viewer. When in command-line mode, mplayer is great.
Hey now, west of Winnipeg there's TWO national highways! And it's mostly a four-lane divided highway, although there are some grade crossings, and crappy 80 km/h sections in Edmonton.
But seriously, there's only really pockets of freeways in Canada, in southern Ontario and Quebec, and around major cities elsewhere. Alberta will probably end up being the first province to have freeways province-wide.

What if the URL is hijacked; via DNS poisoning, HOSTS, a BHO, site hacks, proxy hacks... a URL is unfortunetly, not 100% reliable.
If an attacker uses DNS poisoning or proxy hacks, the CN on the cert would not match the DNS hostname, which would cause an error, or the cert would have an unknown CA, which would also cause an error.
An HTTPS URL is 100% reliable if the hostname matches the CN on the cert, and the cert was issued by a "trusted" CA. "Trusted" in this case means you have the CA's cert (kind of like a public key) bundled with your browser. If you have a way around that, you better alert the internet because you've stumbled upon something huge.
Why should Verisign get special treatment?, because Microsoft used them as a CA? I recall recently a huge stink was made about Windows treating special URLs differently... what about the CA's used by Firefox, Opera, AOL... shouldn't those CA's get equal special treatment? (all URL's are equal, but some are more equal than others)
Isn't it a bad idea to hard-code strings into software? does that same CRL URL apply world-wide and forever? imagine if between 2000 and 2007 Verisign went bankrupt, got bought by AOL/Time/Warner, or decided to change it's name to 'SuperAwesomeSign.com'? What if the nature of internet addressing chages? Unicode, IPv6,.xxx...
IE doesn't hardcode strings, so much as it bundles certs from all the major CAs. These certs expire eventually, which is why, for example, Netcape 2.x will no longer work with HTTPS, and why Microsoft offers a "root certificate update" once in a while. The bundled CAs are the reason that SSL verification can be automated in the first place. Those certs never have to be transferred over the network, because they came bundled with your OS or web browser.
The GP obviously prefers a top loader, and is taking the position of a hypothetical "idiot" who's buying into the latest water-efficient front-loaders. Judging by most of your responses, you seem to understand that, but what's up with 3a? He didn't go to arts college, his hypothetical "idiot" did.
I also think that with point 2, I think he's saying that after you beat the dirt out and surround the grease with soap, you still need to flush it away with lots of water. It's a weak point though, because front loaders seem to do the job just fine.
Anyway, to weigh in on this argument, the front loaders I've used have all been really slow, like 45 minutes to complete a cycle. I always preferred the 25-minute top loaders so I could get the hell out of the laundromat quicker. But I'm in Canada, where like the US, front loaders were rare until 5 years ago.

You need to patch your kernel for security fixes, not install the newest kernel every time. This is what some vendors do. When I install a release of SuSE (say 9.1), I know that every kernel update for that release will be based on the same source (say, 2.6.11 with patches and certain options enabled).
OpenBSD is somewhat like this, too. Their sendmail security advisories don't say "upgrade to sendmail 8.13.6", they say "apply this patch to your existing 8.12 source". That way the update never introduces new behaviour or compatibility issues.
Come on. He's asking for money, not code changes. On that level, GPL-licensed code and BSD-licensed code are the same. A company like Linksys could use the Linux kernel in their routers without giving a cent to Linus or the hundreds of others.

They're both larger-capacity discs than DVD. Blu-Ray just happens to have a higher capacity. The capacity of Blu-ray is 25GB per layer, whereas HD-DVD is 15 (or 20GB?) per layer.
The 930BF doesn't perform. I sit close enough to my monitor that I could notice a difference in contrast between the middle and bottom of the display. The reason for this is the poor viewing angle (+/- 170 I think) and 700:1 contrast ratio. Admittedly, 700:1 is better than the cheap deals you usually see from companies like ASUS, but you still lose the difference between light gray and white.
I ended up returning the monitor and getting a Dell for about $50 more that had a viewing angle of +/- 178 and 800:1 contrast. The difference is striking. Plus I can adjust the height of the stand.
Samsung's 1000:1 contrast LCD's like the 910T, on the other hand, are beautiful. I just didn't want to drop $250 more (at the time).
You can't give students notes. Unless you're the type to transcribe every word the prof says, notes are whatever you need to write down while you're listening to the lecture and focusing on what's being said. That varies from student to student. If you want some written materal that covers the subject at hand, you've got the textbook.
I think this professor has a great idea. If you remove all distractions, and force yourself to not think about anything but the lecture, you have a much better chance of learning the material. If you need your notes on the laptop to keep yourself organized, type them in later.
